A man runs at a speed of 4 m/s to overtake a standing bus. When he is om behind the door (t=0), the bus moves forward and continues with a constant acceleration of 1.2 m/s^2. How long does it take for the man to gain the door?

True or false: the revolution of the earth creates day and night as it rotates around the sun

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Which situation will produce the greatest change of momentum
